A group of BMX bicyclists were nearly run down by a pick-up truck on Long Island. The driver then sped away, but not before prompting a tense standoff with the teenaged bikers. This is not the first time the incident has happened, and neighbors fear it won't be the last.

The incident happened last Saturday in Babylon Village. Some of the bikers pounded on a truck, which nearly struck one of them. The driver swung back around moments later, as a few of them armed with a Go-Pro egged him on.

Police in Suffolk County's First Precinct are now investigating. The truck driver was not the only one who felt threatened that day.

"We received eight or so calls, and there's videos up, where the big lists are just basically in the street, blocking the streets," says Suffolk County Police Inspector Matthew Lewis.

There are at least 50 people in some cases, and last Saturday, Mike Walsh says they surrounded his 16-year-old son who has autism."These kids were harassing him - it was very disconcerting. It's coming to my neighborhood. I don't like that," says Walsh.

Police are studying many YouTube videos and pursuing this one as a criminal investigation.The bikers say they are not trying to do anything bad and that they just want police to understand that they are having fun.
